The stilts increase a persons height by 1.5 yards. if bonnie, who is 5 feet and 7 inches tall, walks with the stilts, how tall will she be?

There's three feet in a yard and if you have one yard that's already 3 feet then add half a yard (half of three) that's 1.5 feet. Add 4 feet to 5 feet then add the six inches to seven inches because 6 inches is half of a foot, and you will end up with

10'1
